Duplicated genes are often referred to as paralogous genes, which form gene families. Several authors have tabulated the distribution of gene family size for a few completely sequenced genomes [11,12] and this varies substantially among species and gene families [13]; for instance, the biggest gene family in D. melanogaster is the Glossary

A clear distinction between orthologs and paralogs is critical for the construction of a robust evolutionary classification of genes and Abstract Orthology and paralogy are two different types of homology, depending on whether the genes in question derive from a duplication event or a speciation event. Homologous, Orthologous and Paralogous Genes - Li - - Major Reference Works - Wiley Online Library If the paralogous genes were still functionally related there is likely to be redundancy between them, so a SNP in one of the copies may not manifest at all. A SNP that affects a sub-trait specific to one of the copies would need to have a massive effect (or the study would require a phenomonal sample size) to find it (unless it was a targeted Homologous sequences are paralogous if they were created by a duplication event within the genome. For gene duplication events, if a gene in an organism is duplicated to occupy two different positions in the same genome, then the two copies are paralogous. Paralogous genes often belong to the same species. Note that paralogous genes are homologous genes that occur within one species and have diverged after a duplication event.

paralogous Describing homologous genes that have arisen by duplication of an ancestral gene. The copies thus evolve side by side (‘in parallel’) in the genome of subsequent lineages, irrespective of speciation events, and hence display similarity of base sequence and, possibly, function.

Multiple copies of znf143 that express at different times could contribute to a more finely-tuned dosage effect that contributes to the overall fitness of the zebrafish during development. Paralogous genes organized as a gene cluster can rapidly evolve by recombination between misaligned paralogs during meiosis, leading to duplications, deletions, and novel chimeric genes.

The two Pax6 gene homologs eyeless and twin of eyeless play decisive early roles in Drosophila eye development. Strong mutants of twin of eyeless or of 

Paralogs can be split into in-paralogs (paralogous pairs that arose after a speciation event) and out-paralogs (paralogous pairs that arose before a speciation event). Paralogous genes often have different functions and, therefore, less sequence similarity than orthologs. As for acquiring novel functions without duplication, believe me I know, I have spent the last couple of years working on moonlighting proteins :). $\endgroup$ – terdon Oct 19 '12 at 18:45 Learn about Homologous, Orthologous, Paralogous, Analogous, Homeologous sequences and alleles (homozygous, heterozygous, hemizygous) 2020-10-08 · In plants, each ribosomal protein (RP) is encoded by a small gene family but it is largely unknown whether the family members are functionally diversified.

2011-02-04 · In-paralogous genes are essentially paralogous genes. The nomenclature helps in distinguishing different classes of genes derived from the divergence of lineages (aka events leading to speciation) and the duplication within a lineage when multiple taxa are compared.
